MCP1827S-1202E/EB

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MCP1827S-1202E/EB is a fixed-output low-dropout (LDO) voltage regulator manufactured by Microchip Technology. It provides a stable 1.2 V output with a maximum current capacity of 1.5 A. The device operates within an input voltage range of 2.3 V to 6 V and features a typical dropout voltage of 330 mV at full load, rising to a maximum of 600 mV at 1.5 A. Quiescent current is specified at 120 µA. Line regulation is 0.05 %/V, and load regulation is 0.5 %. The unit is housed in a DDPAK-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix EB corresponds to the tube packaging configuration when ordering. Confirm that the DDPAK-3 footprint matches the target PCB design constraints. Ensure compliance with RoHS directives and check for any recent product change notifications regarding manufacturing site updates or material substitutions before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when applications require higher current delivery than standard 1 A LDOs while maintaining low dropout characteristics. Compare against the MCP1826 series if lower current requirements allow for smaller package options. Consider the 120 µA quiescent current impact on overall system standby power consumption relative to ultra-low Iq alternatives.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
